A tube of length L and radius R is joinced to another tube of length (L)/(3) and radius (R)/(2) . A fluid is flowing through this joint tube. If the pressure difference across the first tube is P then pressure difference across the second tube is

A fluid is flowing through a tube of length L. The radius of the tube is r and the velocity of the fluid is v. If the radius of the tube is increased to 2r, then what will be the new velocity?

Introduction OF fluids||Assumptions||Concept OF pressure

The pressure of a gas of volume 22.4 l is 3 atm at certain temperature. Then find the pressure of the gas of volume 44.8 l at the same temperature.

A tube in vertical plane is shown in figure. It is filled with a liquid of density rho and its end B is closed. Then the force exerted by the fluid on the tube at end B will be : [Neglect atmospheric pressure and assume the radius of the tube to be negligible in comparison to l ]

If the lengths of the arms of a physical balance are l_(1) and l_(2) and a salesman weighs out twice to a customer articles of mass M by putting weughts first in one pan and then in the other, shown that the salesman is a loser by M[((l_(1)-l_(2))^(2))/(l_(1)l_(2))] .

A horizontally orientd tube of length l rotates with a constant angular velocity omega about a stationary vertical axis. XX passing through end A. The tube is filled with ideal fluid. The end A of tube is having pressure P_(0) . The closed end B has a small hole and at time t = 0, the fluid column has length of l. Find velocity of fluid relative to tube at the instant t = 0
